' HEEL Filed Dec. 17. 1929 2 Sheets-Sheet 2 INVVENTOR @5307? Zia/yer Patented Mar. 24, 1931 JOSEPH BURGER, F BROOKLYN, NEW YORK HEEL Application filed December 17, 1929. 7 Serial No. 414,630.

This machine relates particularly, though not exclusively, to heels of the type covered inP-atent 1,792,965, of February 17, 1931, and made up of a wooden core with a covering of leather or material having the characteristics or appearance of leather.

A. special feature of such heels is that they are lined, streaked, striped or otherwise made up as the edges of the lifts of a solid leather heel.

Such effects are obtained in various ways and one of such ways is to cut or groove definite lines in the leather or other heel covering, spaced approximately the thickness of the regular leather lifts.

. The present invention provides a machine for automatically pressing, cutting or forming the lift-edge grooves in the heel cover.

The objects of the invention, in addition to the broad idea of providin a practical machine for the purpose stated are to provide such apparatus in simple, inexpensive form, which can be readily employed to effect the results desired, which can be controlled or adjusted to meet different requirements and which will be generally eflicient for the intended uses.

The objects mentioned and others, as will appear, arev attained by certain novel features of construction, combinations and relations of parts as hereinafter definitely pointed out and broadly claimed. a

The drawings accompanying and forming part of this specification illustrate certain practical embodiments of the invention, but as such are primarily for purposes of disclosure, it will be understood the structure may vary as regards these illustrations without departure from the true spirit and basic scope of the invention.

Fig. 1 is a top plan view of a machine embodying the principles of the invention; Fig. 2 is a front or face view of the same; Fig. 3 is an enlarged cross-sectional detail, this view being taken as on substantially the planeof line 3-3 of Fig. 2; Figs. 1 and 5 are edge and face views respectively of another form of the machine, differing from the first particularly in that rotary blades or knives are used in place of reciprocating knives and are adapted for lining across the breast of the heel as well as the outer heel surfaces; Fig. 6is an edge view of the rotary blade employed in the empodim ent of the machine shown in Figs. 4: anc 5. p In the machinelshown in Figs. 1 to 3 inclusive', the work of lining or grooving the heel is accomplished by reciprocating or oscillating blades or bars 7, the same being shown as all 'pivotally mounted at one end at 8 on a block 9 reciprocating in guides 10 under impulse of a link 11 connected with said block at 12 and actuated by an eccentric or crank 13. This crank is shown provided on one end of the shaft 14 suitably journalled in a bearing 15 and carrying a pulley 16 over which passes a belt 17 from a pulley 18 operated by motor 19. P

The bars 7 are shown lying close together in fiat face to] face engagement against a back wall 20 which provides a gage against which the heel indicatedat 21 is rested during the scoring, cuttingor lining operation. These bars or blades may be of approxi mately the thickness of ordinary top lifts and they are indicated as havingedges 22. These edges may be sharp enough to actually out into the heel or heel cover, or they may be relatively dull, so as to simply press or compact or groove the heel or heel material without actually cutting into the same. The cutting or pressing operation also depends upon and'can be controlled to an extent by the speed of movement and extent of reciprocation of the blades and the time and pressure with which the heel is engaged therewith. V

A certain amountof pressure is usually desirable and for the purpose, presser bars 23 are shown pivoted at 24 and designed to bear at their free ends'each on one of the lining blades. These presser bars may have sufficient weight of themselves or they may be loaded by means of special weights 25 shown as removably hooked to the free ends of the bars at 26.

The complete gang of marking or cutting blades may be used as a unit or only'a single one or certain selected ones of the blades be operated. In the illustration, this is made possible by permitting the blades and the pressure bars to be thrown upward and supported there out of service relation. This particular condition is illustrated in Figs. 1 and 2, where the front blade or marker as it may begenerically termed and its pressure bar'are shown both'raised at their free ends and 'slidin'gly resting on a table orsupport 27 detachably secured at 28 on'thetop of a post 29. This support or rest 2"('--is made quickly detachable, so that it can be easily taken out of the way of the markers and pressure bars and then be slipped into supporting position beneath One o'r any selected number of the pairs of bars. The marker bars which have then been raised into this supported inactive position will simply oscillate idly over one edge of the support while the weights or pressure bars rest idly on the opposite edge or on top of the bars with which they ordinarily coop erate.

To prevent the markers from dropping down too low and 'to give them an initial or starting position, a lower support is shown at 30 detachably secured at 31 'on the post. This second rest permits the markers to ride idly back and forth, when the machine is running, before the heel is inserted in the machine and does not interfere with the several markers rising inoreor less as required to follow the contour of the heel.

The ordinary method of using themachine is to insert the heel beneath the marker blades as in Fig. 2 with the heel seat end against the face of the gage plate and then by lifting and rotating the heel, in this position to cause the markers to ride over and around the outer surface of the heel, producing the lift edge markings 32 in the course of such combined movements.

These markings, it will be obvious, may be made in the heel coverings or in the bare heels and may be accompanied then or later, as desired, with the application of paint, dye, coloring or finishing material to emphasize or otherwise bring out the lift-edge effect. In the case of grooving or scoring the bare uncovered heels, it will be understood that the cover, when afterwards applied, may be pressed into the score marks as disclosed in my application above referred to to bring out the lift edge effects.

he heels maybe lined or marked either their full height or for a part of their height and they maybe marked all in the single operation or in two or more separate operations. In Fig. 3, it will be seen that only the upper portion of the heel is being marked in this operation.

This leaves the lower half of the heel free to be grasped as a handle for inserting and rotating the heel in the machine. After this first operation, the heel may be withdrawn and inserted in the machine in reversed relation with the top illustrated the markers are in the form of small rotary discs 7a journalled at 34 in the lower ends of slide bars 35 vertically independently shiftable in face to face relation within g'uides36. These scoring, cutting or generally speaking marking wheels are "each independently driven in the present dlsc'losure by spring belts 37 operating in pulley' grooves 38 in the sides of the discs and over suitable pulleys 39 on the motor shaft 40.

In this second embodiment, the downward movement of the markers is determined by a rest or stop 41 engaging shoulders at 42 in the edges of the slide bars 35. Shoulders 43 opposed to these first mentioned shoulders, by cooperation with the same stop, limit the lifting movements of these bars.

Any of the markers in this particular machine may be lifted up out of service position i and then be secured in that relation by a bolt 44 threaded in the upper slide bracket 36 at 45 and adapted by the turning in. this screw bearing to be projected into an opening or openings 46 in one or more of the lifted marker bars. One advantage in this second form of the invention, is that these small diameter markers may be used to score or otherwise mark the more or less transversely concave breast face 47 of the heel. same time it will be observed that these same markers may be employed to carry the markers entirely around about the outside of the heel. In fact, in this form of the invention, the complete periphery of the heel may be marked in one and the same continuing operation. Special means maybe employed, if desired, for holding and shifting the heel under the markers, for instance, a rotary spindle or jack on which the heel is tempo rarily secured by its end face or faces.

It will be realized that both methods of marking have'their own advantages, the reciprocating action being best for certain types of work and the rotary marking for other types of work. The first machine for example, may be employed for finishing the outer convex portions of the heel and the second machine be used for finishing the so-called inner orconcave breast portions of the heel.

The selective use of the two machines also may be determined bythe nature of the heel coverings, the particular effects desired, etc.
